Efficacious phenol-free mycobactericidal liquid compositions having low odor and irritation potential are disclosed. These compositions consist of a solvent containing a glycol, a 2 to 6 carbon atom aldehyde, specific anionic surfactants, and buffer salts to stabilize the pH in the 6 to 7.4 range. The ratio of glycol to aldehyde is comprised between 0.1 and 6.0. The lower this ratio, the greater the mycobactericidal activity. The new odorless compositions can kill $i(Mycobacterium tuberculosis) (EPA quantitative procedure) in 10 minutes or less at 20 C. L'invention concerne des compositions liquides mycobactéricides efficaces exemptes de phénol, présentant un faible potentiel odorant et irritant. Ces compositions se composent d'un solvant contenant un glycol, un aldéhyde contenant 2 à 6 atomes de carbone, des tensio-actifs anioniques spécifiques, ainsi que des sels tampons destinés à stabiliser le pH dans une plage comprise entre 6 et 7,4. Le rapport entre le glycol et l'aldéhyde est compris entre 0,1 et 6,0. L'activité mycobactéricide augmente lorsque le rapport diminue. Ces nouvelles compositions inodores peuvent tuer le Mycobacterium tuberculosis (procédure quantitative EPA) en 10 minutes ou moins à 20 °C.
